# vdev_id: udev helper to generate user-friendly names for JBOD disks
|
||||
#
|
||||
# This script parses the file /etc/zfs/vdev_id.conf to map a
|
||||
# physical path in a storage topology to a channel name. The
|
||||
# channel name is combined with a disk enclosure slot number to
|
||||
# create an alias that reflects the physical location of the drive.
|
||||
# This is particularly helpful when it comes to tasks like replacing
|
||||
# failed drives. Slot numbers may also be re-mapped in case the
|
||||
# default numbering is unsatisfactory. The drive aliases will be
|
||||
# created as symbolic links in /dev/disk/by-vdev.
|
||||
#
|
||||
# The currently supported topologies are sas_direct and sas_switch.
|
||||
# A multipath mode is supported in which dm-mpath devices are
|
||||
# handled by examining the first-listed running component disk. In
|
||||
# multipath mode the configuration file should contain a channel
|
||||
# definition with the same name for each path to a given enclosure.
|
||||
#
|
||||
# The alias keyword provides a simple way to map already-existing
|
||||
# device symlinks to more convenient names. It is suitable for
|
||||
# small, static configurations or for sites that have some automated
|
||||
# way to generate the mapping file.
